With Qin Fengming's current abilities, he could certainly sustain a full-force release of soul energy to activate the runes for an entire month. But making his three nascent souls do the same was rather beyond him.
At this point, Qin Fengming had little soul energy left within him.
Had he not been able to forcibly absorb soul stone energy from time to time between manipulating the runes, his soul energy would have been exhausted long ago. During the process, however, only when the runes stabilized within the restrictive spells did he have a fleeting moment to divide his attention and absorb soul stone energy.
The restrictive spells on the stone doors of these chambers had exceeded even Qin Fengming's expectations.
"Burst!" Seated cross-legged in the spacious cave dwelling, Qin Fengming suddenly shouted. As his voice rang out, a series of deafening cracks erupted from the sixteen chamber doors, their shimmering light flickering incessantly.
Blazes of dazzling light, accompanied by violent surges of energy, abruptly flared across the sixteen stone doors, engulfing the entire cavern in an instant.
An immense, swelling aura churned through the air, and waves of restrictive spell energy battered the vast cavern. Qin Fengming remained seated cross-legged within it, without moving an inch.
After an entire month of working his technique, he had finally broken the restrictive spells on the stone doors in this cavern, at the cost of a tremendous amount of his soul energy.
As the surging energy dissipated, Qin Fengming looked at the exposed stone doors but did not rise, remaining seated on the ground.
"Congratulations on breaking the restrictive spells here, Senior." As the aura of the restrictive spells faded, Zhou Chu's congratulatory voice rang out within the cavern.
Although he offered his congratulations, Zhou Chu did not enter the cave dwelling.
